CNN/Money has a roundup here of John Roberts' role in business litigation. He argued before the Supreme Court that a Toyota factory worker with carpal tunnel syndrome was not entitled to claim the protections of the Americans with Disabilities Act; his position on that will be hard for opponents to demonize, however, since the Court endorsed it 9-0. And while at Hogan & Hartson he argued unsuccessfully on behalf of state governments suing Microsoft on behalf of a breakup remedy. This probably indicates that he is not a member of one particular subset of right-of-center lawyers, namely the type that 1) disapproves of the states' Microsoft stance on libertarian principle and 2) though working at a big Washington law firm, manages to avoid handling all ideologically uncongenial matters or clients. Given the nature of big Washington law-firm practice, however, it is not clear that the set of lawyers who meet the second criterion is very much larger than the empty set to begin with.
